[0002] Visual inspection refers to the process of converting the captured target into an image signal through a machine vision product (i.e., an image capture device, which is divided into CMOS and CCD), and transmitting it to a dedicated image processing system, which converts it into a digital signal based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on site based on the results of the judgment. Visual inspection is increasingly used in areas such as product quality control, automated production lines and defect detection. In order to adapt to objects of different types and sizes to be inspected, it is necessary to fix the objects to be inspected by a fixture. When the existing fixture fixes the object, the number of contact points between the fixture and the object is fixed. If the object to be fixed is of an irregular shape, the fixture cannot stably contact the object, and the object is easy to loosen during the inspection process. In addition, when fixing the object, personnel are required to manually twist the fixing structure, which increases the difficulty of fixing the object. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions:

[0026] An adjustable universal visual inspection fixture comprises a support member 1 arranged below a visual inspection camera, the top of the support member 1 is slidably connected with N limit members 2 along a circular path, N ≥ 2, the limit member 2 comprises a supporting part and a limit member which moves up and down relative to the supporting part, the supporting part is connected to the limit member, and a clamping space for clamping an object is formed between the plurality of limit members.

[0027] Through the above technical solution, when personnel need to fix an object for visual inspection, the support member 1 is fixed under the visual inspection camera. After the support member 1 is fixed, the personnel take the number of limit members 2 required by the personnel, and connect the support part with the support member 1, and cooperate through a circular path to make the support part slide, thereby adjusting the position of the support part, and then adjusting the position of the limit part. When the limit part is adjusted, the clamping space formed between the multiple limit parts is used to contact the object, thereby fixing the object, and by adjusting the number of limit members 2, the number of contact points of the device contacting the object can be adjusted, so that the edge of the device contacts the special-shaped workpiece, allowing personnel to detect the object through the visual inspection camera.

[0028] Specifically, in one embodiment, regarding the above-mentioned support member 1, as Figure 1-Figure 3 As shown, the support member 1 includes a base 13;

[0029] The top of the base 13 is sunken to form an annular groove 12 , and the supporting part is slidably connected to the inside of the annular groove 12 .

[0030] In this embodiment, before detecting an object, the base 13 is placed under the visual detection camera and fixed. The supporting part is connected through the annular groove 12 on the base 13. The position of the supporting part can be adjusted by pulling the supporting part to slide in the annular groove 12, and then the position of the limiting part can be adjusted, so that the limiting part can be fixed by contacting the object.

[0031] Preferably, in order to facilitate the fixing of the base 13, the base 13 is symmetrically fixedly connected to the side panels 11 on both sides, and the side panels 11 are penetrated by screws 15. When the base 13 is placed at the position required by the personnel, the screw 15 is aligned with other objects and rotated to allow the screw 15 to enter the other objects until the screw 15 hits the side panels 11, thereby fixing the base 13.

[0032] In addition, in the present invention, regarding the above-mentioned supporting part, as Figure 1 , Figure 3 , Figure 4 As shown, the support portion includes a base ring 29;

[0033] A connecting rod 28 is screwed and connected to the inside of the base ring 29 along its axis.

[0034] In this embodiment, when personnel need to adjust the number and position of the limiting parts, they take the base rings 29 of the number they need, connect the base rings 29 to the annular grooves 12, pull the base rings 29, and then adjust the number and position of the base rings 29 in the annular grooves 12, screw the connecting rod 28 and the base ring 29 together until the bottom of the connecting rod 28 contacts the base 13, and then fix the position of the base ring 29 to achieve the purpose of adjusting the number and position of the limiting parts.

[0035] Furthermore, regarding how the annular groove 12 is connected to the base ring 29, as shown in FIG. Figure 1-Figure 4 As shown, the annular groove 12 includes a coaxially arranged guide groove and a limit groove, and the limit groove is located above the guide groove, the width of the guide groove is greater than the width of the limit groove, and a through placement hole 14 is opened on the top of the base 13, and the placement hole 14 is located on the limit groove.

[0036] In this embodiment, after a person takes the base ring 29, the base ring 29 is passed through the placement hole 14 through the limiting groove, and the base ring 29 is placed in the guide groove. After the base ring 29 is placed, the base ring 29 is pulled to adjust the position of the base ring 29, and the connecting rod 28 is screwed and connected to the base ring 29 so that the bottom of the connecting rod 28 contacts the base 13 to fix the position of the base ring 29. According to the above steps, the base rings 29 required by the user are fixed at the positions required by the person in the guide groove, thereby completing the adjustment of the number and position of the limiting parts.

[0037] Preferably, the base ring 29 is slidably connected to the inside of the guide groove, and one end of the connecting rod 28 passes through the limiting groove and extends to the top of the base 13.

[0038] In addition, in the present utility model, regarding the above-mentioned limiting part, as Figure 1 , Figure 4 As shown, the limiting part includes a screw ring 25, which is screwed on the connecting rod 28 and is located above the base ring 29. The screw ring 25 is symmetrically fixedly connected to two elastic members 23 on its circumference, and a clamping plate 22 is fixedly connected between the free ends of the two elastic members 23.

[0039] In this embodiment, after the number and position of the base ring 29 are adjusted, the screw ring 25 is screwed together with the connecting rod 28, and the screw ring 25 is fixed on the connecting rod 28. The Keen people complete the position adjustment of the splint 22. When personnel need to fix an object, the object to be fixed is placed between multiple splints 22, and the splint 22 is pushed by the object to move the splint 22. When the splint 22 moves, the elastic part 23 is compressed, and the elastic part 23 generates a reverse force, so that the splint 22 automatically resists the object, and then fixes the object, making it easier for personnel to visually inspect the object.

[0040] Furthermore, when the clamping plate 22 contacts an object, in order to make the object more stable, Figure 4 As shown, the flexible pad 21 is bonded to the side of the clamping plate 22 facing away from the elastic member 23 , and the side of the flexible pad 21 away from the clamping plate 22 bulges outward to form an arc-shaped protrusion.

[0041] In this embodiment, when the splint 22 contacts an object, the flexible pad 21 cooperates with the splint 22 to make it more secure when contacting the object.

[0042] When the splint 22 moves, in order to make the splint 22 move more stably, as Figure 4 As shown, guide plates 24 are fixedly connected to both symmetrical sides of the screw ring 25 , guide rods 27 are slidably connected inside the two guide plates 24 , and one end of the two guide rods 27 is fixedly connected to the clamping plate 22 .

[0043] In this embodiment, when the splint 22 moves, the splint 22 will drive the guide rod 27 to move together, and through the cooperation of the guide plate 24, the guide plate 24 will limit the moving direction of the guide rod 27, so that the guide rod 27 moves more smoothly, and the splint 22 moves more smoothly.

[0044] Preferably, a connecting plate 26 is fixedly connected between the free ends of the two guide rods 27, and the movement of the clamping plate 22 is made more stable through the cooperation of the connecting plate 26.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
